Federal companion document to Central Valley Flood Protection Plan, Regional Flood Management Plans and Integrated Regional Watershed Management Plans BUILDING STRONG What is CVIFMS? 6 A watershed study focused on Sacramento River Basin to develop a comprehensive basin-wide management plan to: Assess watershed characteristics and conditions Identify watershed issues/problems Develop, evaluate and prioritize conceptual alternatives, including structural and non-structural measures for flood risk management, ecosystem restoration and water supply/conservation Incorporate public input and involvement Identify potential spin-off studies under Federal, State and/or local authorities San Joaquin Basin next phase BUILDING STRONG Vision Statement The Federal and State governments share a vision for an integrated flood management system in the Central Valley to provide for safe, healthy and thriving communities while protecting and restoring the environment. The problem is so overwhelming that achievement of this shared vision can only be through pursuit of mutual priorities. The States flood risk management priorities of public safety, environmental stewardship and economic stability match the Federal administrations priorities of protecting the American people, restoring and protecting the environment and improving the nations economy. 7 BUILDING STRONG Ongoing Efforts Leveraged existing information and models from State and USACE projects, including, but not limited to: Central Valley Flood Protection Plan Basin-wide feasibility studies Bay Delta Conservation Plan Regional Plans Sutter Basin Project Yuba River General Reevaluation Project Yuba River Ecosystem Restoration Study West Sacramento General Reevaluation Study American River Watershed Program: Common Features and Folsom Dam Joint Federal Project American River Common Features General Reevaluation Study Sacramento River Bank Protection Project Cache Creek Feasibility Study Delta Islands and Levees Feasibility Study Sacramento-San Joaquin Comprehensive Study 8 BUILDING STRONG Recent Activities Received funding to complete study June 2015 Completed draft determination of federal interest Held two-day stakeholder workshop, August 2015 Completed first draft watershed plan 9 BUILDING STRONG Current Activities Completing sponsor and District Quality Control reviews Will send to South Pacific Division and to public for review this month 10 BUILDING STRONG Planning Goals 11 Flood Risk Management Reduce the risk to public safety from flooding in the Sacramento River Basin; Reduce the risk of damages to residential, agricultural and commercial/industrial areas, and roads and other critical infrastructure due to flooding; Ecosystem Restoration Restore aquatic habitat for the Sacramento River ecosystem; Restore natural stream processes in the Sacramento River; and Water Supply/Conservation Improve water supply reliability and availability BUILDING STRONG Array of Flood Risk Management Management Measures 1.

Re-operate existing dams to conserve more water 3. Enhance/increase groundwater percolation 4. Re-allocate storage in reservoirs 5. Improve existing water conveyance system 14 BUILDING STRONG Watershed divided into 50 Opportunity Areas BUILDING STRONG Array of Measures Applied as Appropriate to each Opportunity Area Sample from CVIFMS features table BUILDING STRONG Qualitative Screening Flood Risk Management Benefits How well the feature could reduce risks to life safety from flooding How well the feature could reduce the consequences associated with flood risk (with an emphasis on improving system resiliency and increasing the integrity of the flood system) How well the feature could reduce risks to critical infrastructure from flooding How well the feature could encourage wise use of the floodplain Water Supply Benefits How well the feature could increase the availability and reliability of water supply (groundwater and surface water) Ecosystem Restoration Benefits How well the feature could increase the area, quality, connectivity and diversity of significant native aquatic and related habitats How well the feature could reduce barriers to fish passage How well the feature could increase natural dynamic hydrologic and geomorphic processes Which types of species the feature could benefit: 1) aquatic, 2) avian, 3) terrestrial or 4) all types (zero = no benefit; low = one type could benefit; medium = two types could benefit; high = all types could benefit) BUILDING STRONG Qualitative Screening Continued FRM, ER and WS Costs The order of magnitude of costs for the feature The order of magnitude of mitigation that could be required for the feature Features that were infeasible, non-policy compliant or that scored zero or less were screened out BUILDING STRONG Conceptual Alternatives (0) No Action Alternative (1) Non-Structural Flood Risk Management (FRM) Alternative (2) Ecosystem Restoration (ER) Alternative (3) Flood Risk Management Alternative (4) Ecosystem Restoration and Flood Risk Management Alternative (4a) Locally developed plan - Central Valley Flood Protection Plan and the draft Conservation Strategy (5) FRM and Water Supply (WS) Alternative (6) FRM, ER and WS Alternative The remaining features were combined into seven conceptual alternatives as follows: BUILDING STRONG Early Off-shoot Study Sacramento River GRR recently initiated study to revision the Sacramento River flood control system for flood risk management and ecosystem restoration BUILDING STRONG Draft Proposed Spin-off Studies Near-term recommended spin-off studies include: Climate Change Assessment under USACE Floodplain Management Services USACE, State, IWR, potentially other Districts in region and climate change experts Develop standard approach for assessing impact of inland climate change on decision criteria in future studies in this region San Joaquin River Watershed Study (CVIFMS Part II) under General Investigations Originally included in this study, but during a re-scoping, San Joaquin River Watershed was recommended to be assessed in a second phase To address remaining portion of Central Valley, consistent with CVFPP and draft Conservation Strategy BUILDING STRONG Draft Proposed Spin-offs Contd Central Valley Reservoir Reoperation Study under General/Special Investigations Operate system in a coordinated manner to optimize benefits Comprehensive investigation of reservoirs within both Sacramento and San Joaquin River Basins (USACE, State, USBR) to optimize operations for FRM, ER and WS across system of reservoirs, incorporating weather forecasts and climate change analysis. Logical and necessary next step to DWRs Phase I and II reoperation studies (http://www.water.ca.gov/system_reop/)http://www.water.ca.gov/system_reop/ System reoperation has potential to produce benefits with little to no construction costs BUILDING STRONG Draft Proposed Spin-offs Contd Middle and Upper Sacramento River Basin Comprehensive Study under General Investigations Multi-purpose ER, FRM and water supply study Study will consider sites located within middle and upper Sacramento River Watershed Study would complement Middle and Upper Sacramento Regional Plan and provide an opportunity to partner with both State and regional group Study area would include Sacramento and Feather Rivers and their tributaries Lower Sacramento River-Delta North area is not included in this recommendation BUILDING STRONG Draft Proposed Spin-offs and Off-shoots Mid- to Long-Term Spin-off and Off-shoot Studies Include: Non-Structural Floodplain Management Services Small-scale, non-structural projects that can provide floodplain mapping, floodplain management plans, emergency plans and flood recovery plans Could provide significant benefits to effected areas for low cost and effort May be critical for small communities, agricultural areas and Tribal communities Upper American River and Tributaries Multi-purpose FRM, WS and ER study along American River and its tributaries (above Folsom Dam and Reservoir). Ecosystem Restoration Studies under Continuing Authorities Program/General Investigations/Tribal Partnership Program Restore ecosystem in more localized areas, including on Tribal lands Areas such as Clear Lake/Upper Cache Creek, Elder Creek, Deer Creek and Stoney Creek among others BUILDING STRONG Draft Proposed Off-shoots Contd Inter-Agency Support Support to sister federal agencies to assist with water resource projects for which USACE has an expertise Planning Assistance to States USACE can provide states, local governments, other non-Federal entities and eligible Tribes assistance in preparation of comprehensive plans for development, utilization and conservation of water and related land resources. Studies could include: water supply/demand, water conservation, water quality, ecosystem restoration and dam safety/failure.
